Can you change the scheduling class of a zone’s processes to FSS without rebooting?
A.
No. Set the zone’s scheduling-class attribute to FSS and reboot.
B.
No. Run dispadmin –d FSS inside the zone, then reboot.
C.
No. Run dispadmin –d FSS in the global zone, then reboot the nonglobal zone.
D.
Yes. Run dispadmin –d FSS inside the zone.
E.
Yes. Run priocntl –s –c FSS –i all inside the zone.
Explanation:
* Syntax:
priocntl -s [-c class] [class-specific options]
[-i idtype] [idlist]
* The priocntl command displays or sets scheduling parameters of the specified process(es). It can also be
used to display the current configuration information for the system’s process scheduler or execute a command
with specified scheduling parameters.
Processes fall into distinct classes with a separate scheduling policy applied to each class. The process classes
currently supported are the real-time class, time-sharing class, interactive class, fair-share class, and the fixed
priority class.
* priocntl options include:
-c
class
Specifies the class to be set. (The valid class arguments are RT for real-time, TS for time-sharing, IA for interactive, FSS for fair-share, or FX for fixed-priority.) If the specified class is not already configured, it is
automatically configured.
-s
Sets the scheduling parameters associated with a set of processes.
